Pez-Sigüenza expedition

The Pez-Sigüenza expedition was a 1693 exploratory journey led by General Andrés de Pez and scientist Carlos de Sigüenza y Góngora which explored the northern Gulf Coast.

The expedition's two ships departed Veracruz on March 25 and arrived in Pensacola Bay on April 7. They began their explorations on April 8, investigating landforms they named "Punta de Sigüenza" and "Barranca de Santo Tomé."

They traveled thence to Mobile Bay and began a scientific exploration there on April 29.

On May 6, after briefly exploring the mouth of the Mississippi River, they began their journey back to Veracruz to report the expedition's findings.

Sigüenza's glowing report of Pensacola Bay, which he called "Bahía Santa María de Galve," led to the Spanish decision to establish a colony there five years later, the Presidio Santa María de Galve.
